The player's agent, Rob Jansen, said earlier this week their camp have had no contact with United and now Ajax have warned it will take a big bid for them to even consider selling the 24-year-old.

"There's some rumblings around Daley, some clubs enquired, but there is no concrete offer. With Manchester United, there is no contact at all," former Arsenal winger Overmars told De Telegraaf.

"We believe that we currently have a strong team and want Daley to stay for another year. Only if the absolute price is paid is a transfer negotiable.

"Daley's management know how we feel at the moment. Next year we will have a much more lenient policy, we are willing to talk with Daley and we will settle for a reasonable price."

Blind has usually operated as a central midfielder for Ajax but also played as a left wing-back and a centre-back for Van Gaal in the World Cup, helping the Netherlands to a third-place finish in Brazil.

Van Gaal is a former Ajax manager himself and worked with both Overmars and current manager Frank de Boer during his first spell in charge in Amsterdam but, while he knows both men well, he is yet to raise the issue of Blind.

The United manager is keen to strengthen his defensive options having endured a torrid start to the new season; the club are yet to win in the Premier League and suffered a humiliating exit to League One outfit MK Dons in the League Cup on Tuesday.
